Bitcoin spot exchange-traded funds (ETFs) extended their longest weekly net inflow run in nine months.

Cointelegraph reported on May 9 that bitcoin spot ETFs recorded net inflows for 6 straight weeks, from the week including April 2 through the week including May 8.

SoSoValue data showed cumulative net inflows of $3.4 billion over the past 6 weeks. The strongest week was the one including April 17, when $996.38 million flowed in. The weakest week was the one including April 2, with net inflows of $22.34 million. The most recent weekly inflow was $622.75 million.

The run is the longest stretch of consecutive net inflows since August last year. In the earlier 7-week streak from June 13 to July 18, 2025, total inflows reached $7.57 billion. In that period, $2.72 billion came in during the week including July 11 and $2.39 billion in the following week, forming much stronger buying pressure.

Recent weekly flows slowed as the week progressed. Early in the week, inflows of $532.21 million and $467.35 million showed a solid pace, but Wednesday inflows fell to $46.33 million. Flows then turned to net outflows of $277.50 million on Thursday and $145.65 million on Friday, weakening sentiment late in the week.

Bitunix analysts pointed to investor caution ahead of the release of U.S. April nonfarm payrolls data. Market expectations called for an increase of 62,000, well below the previous figure of 178,000. By contrast, the ADP employment report released early last week showed an increase of 109,000, stronger than expected. That divergence helped explain split market views on the job situation.

Geopolitical factors were also cited. Bitunix assessed that the United States and Iran again engaged in clashes around the Strait of Hormuz, but both sides are leaving room for negotiations. It also mentioned the possibility that partial understanding may have been reached on some maritime issues.

Bitcoin's spot price also moved with ETF fund flows. Bitcoin fell below $80,000 on Thursday, and a liquidation heat map showed thick liquidity piled up around $78,000. Bitunix said a break of that level could trigger cascading liquidations. It also said short positions are concentrated in the $82,000 to $83,000 range, leaving the market in a tug-of-war phase.

Ethereum spot ETFs returned to weekly net inflows over the same period. Net inflows for the week ended May 8 were $70.49 million. The prior week posted net outflows of $82.47 million, but this week's rebound improved the trend. Earlier, $617.91 million flowed in over 3 weeks from April 10 to April 24, peaking at $275.83 million in the week including April 17.

Ethereum spot ETFs also showed unstable daily flows. Outflows of $103.52 million on Thursday alone wiped out most of the early-week inflows. Inflows were $61.29 million on Monday and $97.57 million on Tuesday, then slowed to $11.57 million on Wednesday. Inflows of $3.57 million returned on Friday, narrowly keeping the week in positive territory.

As a result, the spot crypto ETF market is sustaining weekly inflows centered on bitcoin, but daily fund mobility appears to be rising with macro indicators and geopolitical variables. A key focus in the near term is whether ETF inflows continue and whether bitcoin can defend levels around $80,000.
